Ingredients
For the Brownie Base:
- ½ cup 115 g unsalted butter, melted
- 1 cup 200 g granulated sugar
- 2 large eggs room temperature
- 1 tsp pure vanilla extract
- ⅓ cup 30 g unsweetened cocoa powder
- ½ cup 65 g all-purpose flour
- ¼ tsp baking powder
- ¼ tsp kosher salt
For the Peanut Butter Swirl:
- ⅓ cup 85 g smooth peanut butter (natural or shelf-stable)
- 1 tbsp 12 g powdered sugar
Instructions
Preheat and Prep
- I preheat the oven to 350°F (175°C). I line an 8x8-inch baking pan with parchment paper, leaving overhang for easy removal, and lightly grease for this chocolate peanut butter treat.
Mix Brownie Batter
- In a large bowl, I whisk ½ cup melted butter and 1 cup sugar until smooth. I add 2 eggs and 1 tsp vanilla extract, whisking until glossy. I stir in ⅓ cup cocoa powder, ½ cup flour, ¼ tsp baking powder, and ¼ tsp salt until just combined for this cozy recipe, avoiding overmixing.
Prepare Peanut Butter Swirl
- In a small bowl, I mix ⅓ cup peanut butter with 1 tbsp powdered sugar until smooth. I microwave for 10–15 seconds to loosen slightly, ensuring it’s not oily for this fudgy swirled brownies effect.
Assemble and Swirl
- I spread the brownie batter evenly in the prepared pan. I dollop the peanut butter mixture over the batter in small spoonfuls. Using a butter knife, I gently drag through the surface to create swirls, keeping them shallow to maintain the marbled look for this chocolate peanut butter treat.
Bake and Cool
- I bake for 20–25 minutes, until a toothpick inserted in the center comes out with moist crumbs. I cool in the pan for 30 minutes, then lift out using the parchment and cool completely on a rack. I refrigerate for 30 minutes before cutting for this Peanut Butter Brownies.
Notes
For best flavor and texture, use natural peanut butter that’s creamy but not overly oily. Store brownies in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
